' f Y:Thisinvention relatesto'improvementsinff engines andjp'umps andrefers especially'itow. engines, 'pumps'. and f compressors of 'ethej v.fcranklese` type or .wherein a I swash. plate,VL orfwabbler disc orwheel lmechanism is interposed between the piston velements;and'thelrivingshaftV for the interconver'sion offre'- f to 4provide iimprovements in universal'couplings'for the'y rodsconnecting pistons orcross heads to the wabbler disc or vwheel or' yequivalent memberyTheobject of the invention is whereby fan even distribution y01E load'over all bearing surfaces and "efectivevflexibility l a piston or likerodto va wabbler disc andto 'movement relatively t "and durability willbe ensured.

f v I accomplish the abovementioned object by providing means forconnecting the endsk of rvot pins (arranged at right angles totho'sepassing through the ends of the' rod) mounted ,-inblocks secured tothepiston or crosshead andto the wabbler disci or Wheel;y

The trunnions or pivotfpinsy at each end voi the piston or connectingrod can `bear- 7 franged in vthe same transverse plane or in 1 parallelplanes and the'pivotal devices at the 'endsof ythe rod areconstructedand arranged whereby they canfbe Leasily and quickly assembled anddetached as and when required. The wabbler disc or wheel can be designedand arranged in various ways and in thisl specification, wherever theterm wabbler` disc? is fused, it is intended to include, inter 'alia, acage or memberadapted to be con lnected to the piston or connecting rodswhereby driving pressurecanbe transmitted toa swash plateby means ofinterposed bearing pads or antifrictional members.v
